- The allowable radial direction displacement indicates the case the eccentricity and tilt angle are zero.
- Please insert the shaft up to the marking line J or J₂ correctly.
- The moment of inertia and mass are shown for the maximum shaft hole diameter.
- The recommended shaft tolerance is h6. (For a shaft diameter of 35 mm, it corresponds to a tolerance of +0.010).
- The hub shape (φEₑ) on the taper side of the shaft may differ depending on the manufacturing method and mold.
- The taper shaft diameter can be made to 14 mm.
- The maximum rotational speed does not consider dynamic balance.
- The ◆ symbol indicates that a center nut cannot be used.
